Pulmonary Insufficiency: Melody Valve
2016To date, transcatheter valve replacement for congenital heart disease has focused on the treatment of the dysfunctional right ventricular outflow tract. Following congenital heart disease surgery, the right ventricular outflow tract is often subject to pulmonary regurgitation and/or stenosis, which has been shown to lead to insidious dilation and ...

“Balloon valvulotomy” of congenital pulmonary valve stenosis with tricuspid valve insufficiency
Cardiovascular Radiology, 1979The rare congenital anomaly of pulmonary valve stenosis and massive tricuspid valve insufficiency with intact ventricular septum is a lethal condition without reported survival after attempted treatment. In a neonate suffering from this syndrome, the pulmonary valve stenosis was relieved by rupturing the fused valve with a balloon catheter introduced ...

According to the current guidelines of pulmonary valve replacement (PVR) for pulmonary insufficiency, the age at the time of PVR is becoming younger. However, recent studies have shown that the improvements in mortality have leveled off, making it important to suppress the cumulative lifetime risk of morbidity.

Cardiology in the Young, 2020
AbstractBranch pulmonary artery valve implantation has been reported in larger patients with dysfunctional right ventricular outflow tracts via routine femoral access. Here, we report treatment of severe pulmonary insufficiency with bilateral branch pulmonary artery Melody valve implantation (Medtronic, Minneapolis, Minnesota).

Repair of Pulmonary Valve Insufficiency Using an Autologous Monocusp
The Annals of Thoracic Surgery, 1986A 3 1/2-year-old boy experienced right ventricular failure approximately two years after an operation for critical pulmonic stenosis. Severe pulmonary and tricuspid valvular insufficiency was documented echocardiographically and at cardiac catheterization.

Polytetrafluoroethylene pulmonary valve conduit implantation for chronic pulmonary insufficiency
Cardiology in the Young, 2014AbstractPulmonary valve replacement in patients with congenital cardiac disease is now being performed with more liberal indications in light of the data that chronic pulmonary insufficiency is not a benign lesion. The beneficial effects of valve replacement with low operative mortality and morbidity support this approach.

[Pulmonary Valve Plasty after Postoperative Pulmonary Insufficiency].
Kyobu geka. The Japanese journal of thoracic surgery, 2018A 6-year-old boy (weight 15.5 kg) underwent pulmonary valve plasty using autologous pericardium. He received a diagnosis of aortic coarctation and ventricular septal defect. Total correction was performed at the age of 18 days ( weight 2.2 kg). Intraoperatively, to confirm the position of the ventricular septum defect, we needed to incise from the main

Patent Ductus Arteriosus and Pulmonary Valve Insufficiency; Unusual Clinical Manifestations
Chest, 1970A patient with patent ductus arteriosus is described in whom the combination of pulmonary hypertension and pulmonary insufficiency seem to allow shunting of blood only in diastole. These circumstances produced a peculiar, low-pitched holodiastolic murmur, maximally heard in the second to fourth intercostal space to the left of the sternum.

Organic and relative insufficiency of the pulmonary valve
American Heart Journal, 1937Abstract The pathological and clinical features of 9 cases of pulmonary insufficiency have been presented. The lesion is ordinarily considered very unusual, yet 4 cases have been observed in the Cincinnati General Hospital within the past year. The etiological factors found in this series of cases were: Rheumatic fever, bacterial endocarditis ...

Cardiovascular Research, 1976
In animal experiments regurgitant flow through competent and incompetent pulmonary valves was evaluated with electromagnetic flow velocity catheters by using the ratio of the separately integrated backward and forward flow velocity signals. This ratio was obtained with a special purpose analog computing circuit set by an in-vitro zero flow reference ...
